1g head and 2g head?

[AMPPRC]

are the valves, spring, lifters, valve guides all interchangeable with 1g heads and 2g heads?

The 6bolt block has larger head bolts and more than a few report having to widen the bolt holes for it to be properly installed, key word properly. . . Some have not. But also remember that the head receives oil from one of those holes (farthest left on the radiator side). If it's a tighter fit, then you're likely impeding oil flow to the head: lifter tap, turbo oiling issues, possibly throwing rockers, valve float is possible because the lobe will strike the rocker instead of ramping up the lift. . .

Unless you are lucky enough to have a head off a Hyundai. I will double check but im pretty sure I snagged one the other day that already has the 12mm head bolt holes.

can you guys get a grip, and focus on what the post was meant to be, which is the valvetrain be interchangeable, man I wish defiant was back or at least a replacement that would stop post like this.


To the OP yes they are interchangeable, I honestly can't think of one part that will not work from changing one to another.

Think it was already awnsered in post #9.

Guess I shouldnt have been the BULLY but its stupid remarks like "I laughed when I heard a 2G head was better" comment when its obvious he either didnt research before opening his mouth and types like he is in grade school. Like he said the arguing is done.

yes the parts to swap from a 1g head to a 2g head

Yup right there.

Here is a post i found recently. It seems to be a stock vs stock dyno comparison between the 1g and 2g head.

Any thoughts on how the 1g mani would work so well on a 2g head with no mods to it?

 

[dsmusmc]

I would think it would be a restriction with half the air hitting the ports and the other half just hitting a wall. If you open up the 2G runners to fit 1G runners it defeats the purpuse of using a 2G head.

I saw something on that link about the Hyundai manifold. I had a chance to get one the other day when I got my head off a 95 Sonota and I should have. The plenum is the size of 1G and runners of a 2G and looked to have the same 1G NT throttle body.

That sounds about perfect for this kind of set up. Is it just a standard intake mani on the sonata?

Like this? The plenum is larger than a 1g, the runners are 2g and shorter than either, the throttle body is already a 60mm.

Hmm, where can one find such a IM??

What year and models do they come from? Im guessing 95-99 sonatas with the 2.0.

Is there any more info on those intakes? Someone somewhere has dyno'd it against a stocker haha.

Thats the same one on the 95 Sonota I pulled the head off of. Pretty sure it was a 2.0. I was looking for a Hyundai head forever and came acrosst it when hunting for a ECU.

The local yard has a sonata IM with "ECI MULTI 2000" on it. Is that a comparable Im?

I just peaked on ebay "uugghh" but if somebody is looking here is the link Hyundai 1997 2.0L Sonata Intake Manifold ECI 2000 (EUC) : eBay Motors (item 220480802653 end time Apr-12-10 09:07:36 PDT) I don't know if it will fit but looks very similar to ours and the one in the picture posted. If someone has some dyno work on one Lets hear about it! sonata intake 2g head
